FURNACE-CHARGING APPARATUS. I

To all whom it may concern.-

Be it known that I, EDWIN H. MESSITER a city, county, and State of New Yor have invented a new and useful Furnace-Charging Apparatus, of which the following is a specification.

This invention relates to furnace-charging apparatus and es ecially to apparatus for c arging fln'naces or smelting ead, copper, and other metals requiring simllar treatment.

The present invention 1s closely related in character and in objects to those disclosed in my com anion applications, Serial Nos. 244,676 an 244,677; and it has for its specific object the provision of a furnace-charging a paratus in which the charging material is de ivered from a conveyer having a shifting point of discharge and passes directly downward from the conveyer to the charge within the furnace. p

In attaining the object above stated I emnace and having a tripper or other suitable delivery apparatus arranged ,for reciprocatory movement over the furnace. From or more s outs or conduits extend downward through t e furnace-top, and the furnace-top is so constructed that it will not interfere with the movement of the spouts which extend downward into the furnace.

One form of a v paratus embodying the fea tures mentione 1n the foregoing paragraph is illustrated in the accompanying drawin s and will be hereinafter described in detai but it is to be understood that changes in the apparatus may be made without departing from the spirit of the invention or sacrificing any of its advantages, and I reserve the right to makesnch changes, the scope of the invention being clearly pointed out in the appended claims.

In the drawings, Figure 1 is a view, prmcipally in side elevation, of the top of a furnace provided with a special form of hood and having the char ing apparatus in position above the top 0 the furnace, a portion of the side wall of the hood being broken away to show the lower part of one of the charging-spouts. Fig. '2 is a view 1n vertical section on the line 2 2 ofFi 1. Fig. 3 is a sectional view, on line 3 3 of Fig. 2, of the detions at the top of the hood. to ermit the horizontal movement of the charging-spouts.

Specification of Letters Patent. Application filed February '1, 1906. Serial No- 244,678.

vided with removable lates or doors n on a rid e-piece 3, exten a ove the Patented Jan. 8, 1907.

Referring to the drawings, in which corresponding parts are designated by similar 0 aracters of reference, H designates the hood at the to of the furnace, F desi ates the chargingoor, and T designates t 'e to of the charge within the furnace. The hoo H extends horizontally at one end and is connected:in the usual manner with the flues for removing the fumes that rise from the charge, and at the sides the hood is preferably ro- 'to permit access to the nace for barr' out or for inspection. The top of the hoo above the furnace is preferably formed of a plurality of movable sections '1.' These sections are arranged in two series, as' shown in Fig. 2, each series of sections being ivotally mounted at 2 on one of the side wa s of the hood and having their up er ends resting rnace in the median line. rldge-plece 3 is mounted upon a superstruc ture comprising uprights 4 and suitable transverse pieces 5, and'this su erstructure extends upward beyond the ri ge-piece to aflord su port for the conveyer g and the aparatus for discharging the materialthereom.

The charging apparatus a conveyer-belt C, sup orte idlers 6 and return-nil superstructure above named' The belt C proper comprises upon troughingpasses around a tail-pulley 8 at one end of mg horizontally The ers 7, carried, by 'the the bend-pulleys of a tripper or deliverer,

(designated generally as 9.) This trip er is arranged for travel upon the track-rai s 10, carried by the superstructure in suitable relation to the troughing-idlers, and from the hopper 11 of the tri per spouts 12 extend downward through tfie sectional portion of .the top of the furnace-hood. The spouts 12 are preferably formed in sections, as shown,

the upper section 13 of each' spout being rigidly connected with the hopper 11 and the lower section 14 of each spout being adjustably connected with the upper'section for reasons that will hereinafter a pear. The upper sections- 13 of the spouts iverge from the hopper 11 to straddle the conveyer, and

below the conveyer the ends of the said upper sections converge somewhat to bring the lower sections nearer to the median line of the furnace. Each of the lower spout-sections 14 is shown as pivoted at 15 to one of the upper sections 13, and a lever-ZarrndG which is rigidly attached at its lower end to one of the sections 14, extends upwardly at each side of the hopper 11, where a handwheel 17, which is threaded-one screw 18,-

attached to the hopper, serves to adljust the position of the lOVOIHLI'lll and also t is posi tion of the corresponding spout-section. At the bottom each spout-section'14 is preierably provided with a deflector 19, which may be' or llifie'rent "forms to 'suit' difi erent conditions? In the'form illustrated each deflect-or 19 is suspendedin a hanger or stirrup 20, whieh'is pivoted'at 21 to the corresponding spout-sew tion'14. The sides of achstirrup extend" upwardbeyond the' pivots,- and 'at'the'ir' upper ends theside'pieces of thestirrupsfare' providedwith adjusting devices "22 of any suitable character." These adjusting devices permit the stirrupsor hangers'to be set so-that the" deflectors '19 will throw {the charging material toward the median lineof' thef'urnace 'or toward thesidewalls, as may be desired;

Uponeach of the spout secti-ons 14, in'suit abl'eposition to engage'with the ivoted top sectionsl of the 'furnacehood,I provide a shifting device-23 "which isof trapezoidal" fo'rm; as'shown in Fig. 3, and presentsa tri angular extension at each end along one side of which the cover-sections will slide easily as the slnfter-isadvanced. The triangular ex'- tensions'at each end of each shifter are of precisely the same form, as the sp-outshave a re'ciprocatory movement within the furnacehdod', and 'each end of each shifter serves alternately to raise the cover-sections and to pen mit them to descend raduallyinto their normal position: The s hi fters 23' also serve as'partiahclosiues fo'r the-openin sthat areforrned at the top of thefurnace- 00d when the -cover sect ions are raised to permit the movement of the char mg-spouts, an s pre venting'the escape" 0% 'argeuantities of fumes at the-top of the hood an insuringthe comfort" and convenience of the inspector wheneverhe occupies a positionupon one'of the-footboard's 24;, which are arranged ettln sides of the superstructure at-the levelof the return-'idlers of the conveyer;

The reciprocatorymcvement of the trip per and'the char in'g-s'pouts' necessary to effect the distribution of the charging "material over the topof the charge in the furnace is produced by any suitable apparatus for that purpose su-ch, for exa mple,'as that'disclosed in my companion application, Serial Number 244,676; but the mechanism for-imparting movement tothe tripper forms no partin the present invention, and henceis not described 'in this application? A cable 25 is shown as extending from the top' of the tripper to the reciprocating mechanisrr. adapted to impart movement to the tripperin one :5 direction, and a counterweight 26, attached to the end of a cable 27, which extends in the direction opposite to thecable 25, serves to impart return movement to the tripper.

'n tlleoperation-ofthe chargin ap aratus the char ing material is carried I) t e conveyer-be lt U to the hop )er 11 of'the-tripper 9, into which it is disc arged in a substantially continuous stream. This stream is divided into two streams of substantiall equal size, which pass downwardly through the "charging-spouts 12 and are=distrib1lted in any desircdmannerby the deflectors--19, arranged-beneath the'char lng-spouts." The reciprocatorv movement oil 'the trippermay be controlled adjusting the drivingmeeh 8o anism to effect a uniform distribution'of the charging material over the tdp cf thecharge or to distribute it unevenly if the conditions existing within the'fu'rnace require such *dis tribution. The adjustment of "the*'lower*8 spout-sections 14' to determinetheqndper points of 'disc'har e for thestreams ofchar ingmaterial is 'efle'cte'd bythe=operator wit 1- out leaving thefoothoards 24, and the adju'strnent of the deflectors-beneath tlie charg 9o in'g-spouts may be readily effected by re moving theplates' P, which form parts of the side 1 walls of the I furnace-hood and Teaching through the opcningsleft when the-plates i are removed. 9 5
